I am not sure if you guys know this but when you use Truphone it makes unannounced changes to your phones default calling settings. The normal default calling type is: "cellular", however Truphone changes this to: "Internet" and then proceeds to make ALL calls over the Internet. Even if you are calling your sister in the other room, it goes over the Internet, thus putting money into Truphone's pocket. I have nothing wrong with people making money, but I do have a problem with people making behind the back changes and then, in my opinion, stealing money from me. Let the user beware. Neither Skype, nor Gizmo do this.
If I am incorrect in this assessment, please correct me and show me where I was wrong.
